摘 要
本文对Android系统的特征,系统架构及应用程序构建、开发都做了比较详细的分析。同时结合Google Maps、GPS定位技术,对在android上定位和导航进行了深入的研究,并设计了基于android系统的导航系统。系统使用java语言和eclipse开发工具进行编写。同时给出了详细的系统设计过程、部分界面图及主要功能运行流程图,本文还对开发过程遇到的问题和解决方法进行了讨论。
本系统的主要功能包括手机实时定位,指定地点的寻址,规划导航路径,个人位置跟踪、监视、展示的应用程序。系统中还涉及了数据库和服务器等方面的技术。本系统只限于应用层的探讨,对地图偏移等算法不做深入研究。
系统在导航路径方面做了改进,将路径作为文件记录存储,同时上传服务器。区别于其他同类产品,同时在定位时采用了多种定位方式相互参考,分析研究了Android的GPS定位和网路定位。

Abstract
In this paper, the characteristics of Android system, system architecture and application bui lding, the development has done a more detailed analysis. Combined with Google Maps, GPS po- sitioning technology, positioning and navigation on the android conducted in-depth study and and roid system is designed based on the navigation system. It use java language and eclipse system
development tools to write.At the same time gives a detailed system design process, some interfa- ce flow chart diagram and run the main function, this development process also encountered pro-
blems and solutions are discussed.
The main function of this system include real-time positioning mobile phones, addressing the designated place, planning the navigation path, personal location tracking, monitoring, displ- ay applications. System is also involved in other aspects of the database and server technologies. The system of the application layer only on maps do not do in-depth study migration and other a- lgorithms.
The system has done to improve the navigation path, the path to the record store as a file,
and upload server.Different from other similar products, while positioning method using a variety of cross-reference, Analysis of the Android’s GPS positioning and network positioning.
